The 39-year-old model was onstage Thursday night at the Toys 'R' Us Children's Gala in New York wearing a slinky, black-sequined KaufmanFranco gown slit so high that it was clear to all that she was knicker-less.

But the drawers-free fashion came into full focus when Klum took a tumble alongside co-attendee Martin Short - and her slit gaped open to reveal undergarment-free glutes.

Like Paltrow, Klum had a sense of humor about her experience, tweeting a picture of the fall alongside the caption "(no comment)".
